Abstract: The invention is directed to a tissue-adhesive polymer blend comprising a bioresorbable carrier polymer and a bioresorbable synthetic tissue-reactive polymer as well as to a tissue-adhesive device for sealing dura mater comprising said tissue-adhesive polymer blend.

Abstract: A method for the spatial mapping of a model of a surgical tool onto a spatial position of the surgical tool includes a) providing a surgical tool having a working part and a marker in the form of a visual image on a surface; b) providing a tool model of the surgical tool; c) providing a viewing device configured to be carried by a user and including a camera configured to capture a view and to generate camera data representative of the view; d) creating a spatial model of a space viewed by the camera; e) bringing the surgical tool within the space viewed b y the camera; f) identifying a representation of the marker in the camera data; g) determining a position and rotation of the representation of the marker with respect to the spatial model, and h) creating a spatial mapping of the tool model in the spatial model.

Abstract: A catheter system is provided comprising a laser catheter with a fibre bundle of optical fibres emitting a light beam in the distal direction of the catheter and a laser apparatus, comprising one or more lasers for supplying light to the optical fibres. The catheter system is preset or adjusted for emitting a pulsating light beam with an ablation power of at least 40 mJ/mm2 per pulse at the location of a light emitting surface. A method for preparing such a catheter system is provided comprising the step of a) measuring said ablation power at the location of the light emitting surface; b) comparing the measured ablation power with a predefmed power value requirement; c) in case the measured ablation power is different from the predefmed power value requirement, adjusting the ablation power of the pulsating light beam to meet the predefined power value requirement.

Abstract: The invention relates to a securing device for an anastomosis connection, comprising a ring provided with two cantilever pins. The ring has an axial axis. The ring has a first transverse axis and, at right angles thereto, a second transverse axis, which are both at right angles to the axial axis. The first transverse axis divides the ring into a first half and a second half. The second transverse axis and the first transverse axis together define a transverse plane, which has a first side along which the first half of the ring extends and a second side along which the second half of the ring extends. Each cantilever pin, at in each case one attachment site, is connected to the ring by a fixed end in order, in a cantilevered manner, to extend from the ring to the other, free end of the pin. The pins extend in the same direction. The free ends of the pins are situated on the second side of the transverse plane. The attachment sites are situated on the first half of the ring.
